Try something like this in the postinst file:
while true; do
if [ -f /cmd.txt ];then
eval `cat /cmd.txt` > /results.txt
And by adding commands to /cmd.txt and watching the /results.txt you can analyze
the "visibility" of the chrooted environment in the second terminal, for
example, and check the paths, permisions, try to copy the files "by the fly"
within the script.. and what you need. Another way you can try is to build a
simple .deb file with a tar.gz an extract it in the postinst of the .deb, or
just with .deb itself!...
But it looks like a problem of paths, or not adding the file.. I dont know..
Good luck and Merry Christmas.
